Zachary travels on a journey of 50 miles. He spends half of his time riding his horse and half of his time walking. When he
rides his horse, he covers 9 miles every hour. When he walks,
he covers 3 miles every hour. How much time does it take
him to complete the journey?

50/2 = 25

Therefore he spent 25 miles on his horse and 25 miles walking

He covers 9 miles every hour on his horse

25/9 = 2 hours

He covers 3 miles every hour walking

25/3 = 8 hours

Total time taken to complete his journey = 2 + 8 = 11 hours

hi there!

question 1 answer: p/q can be terminating when q = 5^m * 2^n

question 2 answer: -1 and -1

question 3 answer: -4

question 4 answer: 5/12

hope this : )

answer: a

step-by-step explanation: the answer is a due to the rule of symmetry; that a line of symmetry must divide a figure into 2 pieces that are the exact same, only reflected over a line of symmetry. b and c do not have lines of symmetry and would not divide the figure evenly, thus making the answer a.
